  2. 1. Instrumentation for silicon tracking at the HL-LHC

    Author : Rebecca Carney; Samuel Silverstein; Sara Strandberg; Thomas Schön; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Instrumentation; physics; particle physics; atlas; radiation damage; neuromorphic; kalman filter; fysik; Physics;

    Abstract : In 2027 the Large Hadron Collider (LHC) at CERN will enter a high luminosity phase, deliver- ing 3000 fb 1 over the course of ten years. The High Luminosity LHC (HL-LHC) will increase the instantaneous luminosity delivered by a factor of 5 compared to the current operation pe- riod. READ MORE

  4. 2. Radiation tests of semiconductor detectors

    Author : Valery Chmill; Bengt Lund-Jensen; Richar Brenner; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; radiation physics; materials science; Nuclear physics; Kärnfysik;

    Abstract : This thesis investigates the response of Gallium Arsenide (GaAs) detectors to ionizing irradiation. Detectors based on π-υ junction formed by deep level centers doping. READ MORE

  5. 3. The microdosimetric variance-covariance method used for beam quality characterization in radiation protection and radiation therapy

    Author : Jan Erik Lillhök; Lennart Lindborg; Bernd Grosswendt; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ionizing radiation; radiation quality; radiation protection; radiation therapy; microdosimetry; nanodosimetry; variance-covariance method; Radiological physics; Radiofysik; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : Radiation quality is described by the RBE (relative biological effectiveness) that varies with the ionizing ability of the radiation. Microdosimetric quantities describe distributions of energy imparted to small volumes and can be related to RBE. READ MORE

  6. 4. Measurements of the Top Quark Pair Production Cross Section and an Estimate of the DØ Silicon Detector Lifetime

    Author : Sara Strandberg; Christophe Clément; Barbro Åsman; Steinar Stapnes; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; top quark pair production cross section; silicon radiation damage; DØ detector; Tevatron accelerator; Elementary particle physics; Elementarpartikelfysik; Physics; fysik;

    Abstract : This thesis presents two measurements of the top quark pair production cross section at sqrt{s} = 1.96 TeV using data from the DØ experiment. Both measurements are performed in the dilepton final state and make use of secondary vertex b-tagging. READ MORE

  7. 5. Simulation and analysis of radiation from runaway electrons

    Author : Mathias Hoppe; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tokamak; runaway electrons; synthetic diagnostics; fusion; synchrotron radiation; plasma physics; bremsstrahlung;

    Abstract : Electron runaway constitutes one of the primary threats to future tokamak fusion reactors such as ITER. Successful prevention and mitigation of runaways relies on the development of theoretical models which accurately describe the dynamics of runaway electrons, and these models must in turn be validated in experiments.
